WARPER.

Application filed May 12,

This invention relates to a warper or machine in which a sheet of warps drawn from the spools or creel are wound upon a beam such as is used for the warp supply in a loom. I

It has been the practiceto some extent to dye the warps after they are wound upon the beam, a process which is known as beam dyeing, and improvements which have been made in this method of dyeing have led to a larger use of the method. In beam dyeing, in order that the dye may penetrate evenly and thoroughly the mass of warp on the beam, it is necessary to con trol the tension of the warp wound on the beam and the density of the wound warp mass. These features of tension and density chiefly determine the degree of permeability of the warp on the beam to the dye, the warp beam rests .upon the driving roll of the warper, the pressure is a function of the weight of the warp beam and warp mass, and as the latter increases from nothing to a very considerable amount, this pressure varies within a wide range and materially aifects the density of This variation in pressure, the retarding motionof the creel and of the warper elements acting on the war before it reaches the warp beam, also a set the tension of the warp as it is wound upon the beam.

It is the object of the present invention to provide a warper in which the tension of the warp wound on,the beam and the density of the wound warp mass are controlled as desired and particularly so as to secure the required permeability of the mas to the dye,

It is the object of the invention further to provide a construction in which the prestogether with f preferred form the warp mass;

sure between the driving roll and the warp mass being wound on the warp beam may remain substantially constant and of a required degree during the entire winding operation.

It is the object of the invention further to provide a construction in which the warp beam rotates in fixed relation to the frame of the warper and in which the driving roll is yieldingly pressed into driving contact with the warp mass. Q

The object of the invention is further to provide improved means for controlling the tension of the warp as it is delivered to the beam.

' The object of the invention is further toprovide an improved construction for holding the warp beam in position and for con-' trolling the movement of the warp beam into and from its position on the frame.

These and other objects and features of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings:

Figure 1 is a .side elevation of a warper of a generally familiar type embodying a of the present invention.

Figure 2 is a rear elevation partially broken away of the construction shown in Figure 1.

Figure 3 is a side elevation looking toward the right of Figure. 2 of the carriage for the driving roll and connected parts.

'liigure 4 is a side elevation looking toward the left of Figure 2 of the inside of a portion of the left hand side frame.

The general type of warper which this invention is shown as embodied in is well known and familiar. It'comprises the side frames 1 and 2 which rest upon the floor and are rigidly connected suitable girts, rods and shafts. A main girt 3 isshown extending between the side frames at the rear and bolted thereto at 4. A connecting rod 5 is also shown at the bottom, extending between; the sidesjof the frame, and the sides are}odnnecte(ii-"fiat other;v

points in addition. I

The sheet of warp 6 comesjfrom the usual beam and rest in the creel, passes over, an idler roll 7 journaled at the top of the frame, down around a measuring roll 8, up over'a'second idler roll 9 journaled at the top of the frame, through drop wires 10 and over a third idler roll 11, journaled in a bracket 12 at the front of the frame, to the warp beam upon which 1t is wound.

It is usual to rotate the warp beam to effect the winding of the warp thereon by means of a beam driving roll having peripheral contact with the warp as it is wound on the warp beam. Thus the speed with whic the warp is wound may readily be controlled or maintained constant as deslred, notwithstanding the constant variation 1n the diameter of the warp mass.

An importantv feature of the present 1nvention resides in providing a constructlon in which the warp beam has fixed bearings in the frame, while the beam driving roll is mounted to have bodily movement toward and from the warp beam and is preferably yieldingly maintained with the requisite driving: pressure in contact with the warp being wound on the warp beam.

' In the referred construction illustrated the warp beam 13 is provided at each end with the disks or heads 14 and wi h the axial shaft or spindle 15. The sides of the frame are provided with alined curved seats 16. Cylindrical journal bearings 17 are placed over the ends of the spindle 15 on the warp seats 16. These bearings, and consequently the beam, are held inposition by suitab e means such as'the beam 'lock of novelcoristruction provided.

The beam lock illustrated compr1ses a cap member 18 and a hook member 19. The cap member 18 is pivoted to the frame at 20, extends over the bearing 17 andis pivoted to the hook member ber, when in position, hooks beneath a lug 22 projecting from the frame; The cap member 18 has threaded therein a set screw 23 abutting the bearing 17. It will thus be .seent-hat when the warp beam is in position,

as .shown in Figure 1, and the set screw 23 is' screwed down, the bearing 17 will be locked in ri 'd position ob -the beam. When it 'is desire to remove the warp beam the set screw 23 is turned to release the hook 19, the hook 19 is swung upwardly and the cap member 18 if necessary also, and the warp beam with the bearing 17 is removed.

The frame at each s1de is provided with a forwardly extending bracket 24 curved on its upper surface 25 to form a track merging with the seats 16. This bracket 24 is ivoted u on a vertical pivot 26 to the ame so is at it may be swung back against the frame. These brackets 24 with the cylindrical bearings 17 afford a simple and ractieal meanssfor positioning the warp amfon andreimoving it from the warper.

19 at 21. The hook memneeaeso The warp beam may be pulled on a truck in front of the warper, the bearings 17 slipped over the spindle 15 and then the warp beam rolled up on the tracks 25 into its seat.

After the warp beam is filled and ready for,

removal a truck maybe drawn up in front of the warper, the beam locks released, and the warp beam with the bearings 17 rolled down the tracks 25 on to the truck. The brackets 24 being pivoted, are swung aside when the warp beam is removed so that they will not be caught and broken and will not be in the way.

The beam driving-roll in this invention is mounted for movement toward and from the warp beam and is yieldingly pressed into driving contact with the warp mass. As a preferred construction for securing this result, the driving roll is journalled in a carriage extendin between the ,sides of the warp frame an mounted for a sliding movement in the frame,and preferably in a direction radially 'of the seats 16.

his carriage, one end of which is shown in Figure 3, comprises side plates 27 rigidly connected by a cross girt 28 bolted thereto at 29. The side plates 27 extend upwardly to form the angular projections 30 .and on the exterior faces of the side plates are projections forming guides 31 which fit and 'slide in the track grooves 32 formed on the tracks 32 or away fromthe warp beam. Its v and its yielding moveweight is overcome ment upwardly to bring the driving roll into drivin contact with the warp on the warp beam 1s effected in any desired manner. A simple and practical means for this purpose is illustrated.

The brackets 33 project-rearwardly from the side frames of the warper and in these brackets is journalled a shaft 34 extending transversely of the ries, rigidly connected thereto, a pluralit of large pulleys 35 and a lurality of sma l pulleys 36.. Suitable fiexib e connectors such as chains 37 are connected as at 38 to the carriage and extend over idler pulleys 39 journalled in the frame and are fastened to the small pulleys'36. Other chains 40 are fastened to the pulleys 35 and extend thereabout to weights 41 hanging at the rear. These weights, which may be variedin number and size as required, together with the connectors described, not only serve to counterbalance the carriage and connected parts, but are arranged yleldingly to force the carriage with the driving roll into driving contact with the warp mass on the warp beam and to give the-desired driving pressure. It will be seen that not only may this pressure be varied as required, but by reawarper. This shaft carthe constant variation in son of the principle employed, this pressure- The shaft 34 may be turned by hand in order to raise and lower the carriage when- .axis of the driving roll 48. tion illustrated this is secured by providing usual fast and loose pulleys 54 and 55.- counter shaft 56 is mounted above the main "shaft 53 and has a hearing. at one end in the ever desired- For this purpose the shaft 34 is shown as provided at one end with a gear 42 meshing with a small pinion 43 on a shaft 44 from which projects or over which may be slipped a crank handle 45. A detent 46 is pivoted to the frame at 47 and may be swung upwardly into engagement with the ar 42 to hold it against rotation when the andle is released.- This effects a ready means for use when thewarp beam is to be removed. The operator seizing the handle 45, rotates the shaft 34 sufficiently to lower the driving roll out of contact with the warp beam. The detent 46 is then swung into en-' gagement with the gear 42 to hold the carriage thus depressed.

The beam driving roll 48 is deeply recessed at its ends and the bearings for this roll arein these recesses, so that the driving roll 48 may move up as close as possible toward the center'of the warp beam, allowing the heads 14 to pass down beyond the In the construcjournal brackets 49 bolted at 50 to the ends of the carriage 27, and projecting upwardly and inwardly. At their inner upper ends these brackets are provided with caps 51 forming with the bracket bearings for the shaft 52 of the driving roll.

Suitable means are provided for transmittingrotary movement to the shaft 52 and consequently to the beam driving roll 48, regardless of the position which the carriage may occupy and regardless of the movement of the carriage, for'securing this result herein illustrated. J

The main" driving shaft of the warper 53. is shown extending between the side frames in the rear and near the bottom it carries the side frame 3, and at the other end in a bracket 57 projected forwardly from and bolted to the cross girt 3 at 58. Intermeshing gears 59 on the main shaft and 60 on the counter shaft cause the latterto be rotated from the former- The counter shaft 56 has secured thereto inside the frame, a pinion 61 meshing with a gear 62 journalled on a stub shaft 63 in a link 64 pivoted to the shaft 56. It will thus be seen that, whatever position the gear 62 may occupy-with respect to the pinion 61, it -will always remain in mesh therewith. the carriage 27 and extends parallel with the beam driving rollsh aft 52. This shaft A short shaft 65 is mounted in .p

65 has abearing at its end in the bracket 49 and 'the cap 51 is extendedrearwardly to form the cap for this bearing. At its outer end the shaft 65 has a bearing in a bracket 66 secured at 67 to the side plate 27 of the At its outer end this shaft 65 has secured thereto a gear 68 meshing with the,

carriage.

gear 62. A link 69 is pivoted at one end to thesliaft 63 and at the other end tothe shaft 65, so that whatever position the formenmay take. with respect to the latter the gears 62 and 68 will always be in mesh. The shaft 65 drives the beam driving roll 48 and for that purpose is provided with a pinion 70 at its inner end meshing with a gear 71 on the shaft 52, both of these gears being well within the recess in the end of the beam drivin roll.

It Wlll thus be seen that as the carriage 27 rises and falls or moves toward and. away from the warp beam, the train of gears at all times remains in mesh causing the motion to be transmitted to the beam driving roll 48.

The tension of the warp is largely controlled by the peripheral speedof the roll 8 with respect to the peripheral speed of the warp mass as it is wound on the warp beam. This roll 8 is referred to as the measuring roll because it is commonly employed to measure the length of warp wound on .to'the beam. By varying the peripheral speed of this roll 8 with respect to that of the warp mass on the warp beam, it is possible to give any desired tension to the warp.. This invention therefore provides means for adjusting or varying the peripheral speed of the measuring roll 8 and a preferred form of means for that purpose is herein illustrated.

A pair of oppositely disposed parallel frustro-conical pulleys are mounted .between the measuring roll 8 and the shaft 56. The lower 72 of these pulleys is journaled in a frame 73 mounted to swing vertically on and about the shaft 74 which shaft is journaled at one end in a bracket7 5 mounted onthe cross girt 3 and at the other end in the side frame 1. The upper 76 of these pulleys-is A journaled on a shaft 77 carried at its ends in the side frames 1 and 2 and at its center inthe plate 7 8. The. plate 78 is carried at its upper end by a tie rod 79 connectin the sides of the warper and at its lower an is secured to the bracket 75. A belt 80 connects the two pulleys 72 and 76 and sup rts the former with its pivoted frame 73 and is thus maintained under proper driving tension.

The shaft 74 carries a sprocket wheel 81 which drives a sprocket chain 82 running over a sprocket wheel 83 on the shaft 84 of the measuring roll. it will be remembered is driven from the 4 ower shaft 53, carries a sprocket wheel 85 which drives a sprocket chain 86 which in turn runs over a sprocket wheel 87 and The shaft 56, whi

therefore drives. the shaft 77 and the cone pulley 76. The cone pulley 76 drives the cone pulley 72 through the belt 80 and the cone pulley 72 is provided with a pinion 88 meshing with the gear 89 secured to the sha t 74. It willthus be seen that through thp medium of these connections the measuring roll 8 is rotated from the power shaft of the warper. The peripheral speed of the roll 8 will depend upon the position ofthe belt 80 on the cone pulleys. This position is controlled by a belt shipper. shipper is shown as a bar or plate 90 threaded on to thethreaded shaft 91 which is journaled at its ends in the bracket and the side frame 1. The shipper 90 has a bifurcated forward end sliding on a rod 92 extending between the plate 78 and the side frame 1 and also has a. rearwardly pro jecting end 93. It will thus be seen that as the shaft 91 is rotated in one direction the. shipper 90 will move in one direction or the other lengthwise of the cone pulley andshift the belt, effecting the desired change in the peripheral speed of the measuring roll 8. Anysuitable means may be provided forautomatically or manually rotating the Shaft 91. It is found in practice that amanual control is usually sufficient and for this purpose the end 94 of or the other,

the shaft 91 is formed of polygonal shape to receive a suitable handle or wrench.

Thus is shown a simple and preferred construction embodying the invention and enabling the desired result herein set forth readily to be secured. By varying the weights 41 any desired amount of driving pressure may be secured between the driving roll 48 and the warp mass being Wound upon the warp beam, and by rotating the shaft 94 any desired relation of the peripheral speed of the measuring roll 8 to'the peripheral speed of the warp mass and consequently any desired degree of tension in the warp may .be secured. :Thus the density of the warp mass and the tension of the warp in the mass and consequently the permeability of the warp mass to the dye may readily be controlled to secure any desired conditions.
